Ubuntu14.04配置Detectron,及问题.

安装依赖(txt文件有的就不用了)opencv-python>=3.2 future

源码编译:
make && make ops
编译了一天:PROJECT_SOURCE_DIR为包含PROJECT()的最近一个CMakeLists.txt文件所在的文件夹。
cmake问题 要学着去分析CMakeLists.txt.内容
出现问题1:
CMake Error at cmake/Dependencies.cmake:8 (find_package):
  By not providing "FindCaffe2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Caffe2", but
  CMake did not find one.

  Could not find a package configuration file provided by "Caffe2" with any
  of the following names:

    Caffe2Config.cmake
    caffe2-config.cmake

  Add the installation prefix of "Caffe2" to CMAKE_PREFIX_PATH or set
  "Caffe2_DIR" to a directory containing one of the above files.  If "Caffe2"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:14 (include)

-- Configuring incomplete, errors occurred!
See also "/home/vivian/HelloWorld/tracker/DetectAndTrack/lib/build/CMakeFiles/CMakeOutput.log".
make: *** [ops] Error 1
o check if Caffe2 GPU build was successful
或者
By not providing "FindEigen3.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Eigen3", but
  CMake did not find one.
 
  Could not find a package configuration file provided by "Eigen3" with any
  of the following names:
 
    Eigen3Config.cmake
    eigen3-config.cmake

[也就是找不到Eigen3Config.cmake ]
[解决办法]确保“Caffe2”已安装好.全局搜索 Eigen3Config.cmake,
放到lib/cmake/Modules下,你自己改CMakeLists.txt文件下的路径也行
把
# Add CMake modules.
list(APPEND CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake/Modules)
改成
# Add CMake modules.
set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake/Modules)
find_package(Eigen3  REQUIRED)
